WaveSpring, the buoy that produces electricity from sea waves

Apr 15, 2016 | written by:

The sea, with its waves, is always on the move and for this reason it is a clean and potentially infinite source of energy. Many have tried to fully exploit its potential and the Swedish company CorPower Ocean seems to have done it with unprecedented results. The tool developed is called WaveSpring and it is an innovative floating buoy of about eight meters in diameter anchored to the sea bed, able to store the energy of waves (both those on the surface and those from the depths of the sea) thanks to a special phase converter.

Oscillating in resonance with them, WaveSpring amplifies its ability to capture the movement and consequently the energy produced: a single buoy in open sea is capable of generating about 250 kilowatts of power, enough to cover the electricity needs of 200 homes. CorPower claims that its invention is three times more efficient than devices currently on the market and estimates that as many as 20% of the total electric power on earth could be powered through the waves.

Because the ocean is always on the move, this energy could be more efficient than solar or wind power, which suffer when conditions are not favorable, it is clean just like other renewable and produces zero carbon dioxide emissions. So far, a full-scale prototype has passed with flying colors tests and experiments and the company has announced its intention to put on market the first WaveSpring by 2020.
